In an interview with Russia Today, the world's highest-ranking alien believer explained: "They don’t want to tell us how to run our affairs, they have accepted the fact that this is our planet, and that we have the right to run it, but they are very, very concerned."

"They don’t think we are good stewards of our planet," he added. "We’re clear cutting our forests, we’re polluting our rivers and our lakes, and we’re dumping sewage in the oceans. They don’t like that and they made it very clear."

Extraterrestrials have given us a warning, he said.

"We’re really wrecking our planet and in fact that something dreadful is going to happen to it if we don’t smarten up and change our ways," he said.

"We spend too much time fighting each other, we spend too much money on military expenditures, and not enough on feeding the poor and looking after the homeless and the sick.

"Our future as a species, and here I mean all of the species in the world, is potentially at risk if we don’t figure what’s going on and work together to try and make life more amenable for all of us, and to work with our neighbours from other planets as well."

But he sounded less convincing when describing his own experience with UFOs.

He claims to have seen one, but when asked what it was like he said: "It just looks like a star."

Parkes, told the Northern Echo that he has fathered a child with an alien. In fact, Parkes says he has sex with an extraterrestrial he calls the "Cat Queen" four times a year. In case you're wondering, the kid's name is Zarka.

Unsurprisingly, Parkes says the relationship has put some strain on his marriage with his human wife.
